21761848-1	2011	We utilized a series of pyrimidine analogues modified at O(2), N-3, and N(4)/O(4) to determine if two B family DNA polymerases, human DNA polymerase alpha and herpes simplex virus I DNA polymerase, choose whether to polymerize pyrimidine dNTPs using the same mechanisms they use for purine dNTPs.	pyrimidine	227-237	DNA polymerase alpha 1, catalytic subunit	Homo sapiens	134-154	
1730053-2	1992	The involvement of DNA polymerases alpha, beta, delta, and epsilon in excision repair of pyrimidine dimers was examined using specific inhibitors.	pyrimidine	89-99	DNA polymerase alpha 1, catalytic subunit	Homo sapiens	19-66
